AI Technical Summary

Benefits of technology

The present invention is about a way to make pictures look better by reducing distortion. The method measures how much distortion there is and uses that information to correct the distortion in the picture. This results in a better looking picture with less distortion.

Problems solved by technology

However, in printing of such electro-photographic apparatuses, misalignment of a printing position of image data formed on a sheet may occur and distortion of the image data printed on a sheet may occur.

Abstract

An image processing apparatus includes a forming unit configured to form, on a sheet, a pattern from which at least two lines each connecting two points located at positions parallel to a conveyance direction of the sheet are detectable, a detection unit configured to detect, from the pattern formed by the forming unit, at least two lengths of lines each connecting two points located at positions parallel to the conveyance direction, and an acquisition unit configured to acquire a correction value used when correction is performed so that there is no difference between the lengths of a plurality of lines detected by the detection unit. The forming unit forms an image obtained by correcting a corrected image to be output using the correction value acquired by the acquisition unit.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image processing apparatus that corrects distortion of an image formed on a sheet.[0003]2. Description of the Related Art[0004]Machines capable of realizing image quality similar to that of printing machines have appeared with an improvement of the capability of electro-photographic apparatuses. However, in printing of such electro-photographic apparatuses, misalignment of a printing position of image data formed on a sheet may occur and distortion of the image data printed on a sheet may occur.[0005]To resolve, among several kinds of misalignment of a printing position, misalignment occurring to the front, rear, right, and left sides in a conveyance direction in an image forming apparatus with respect to a printing position of an image printed on the front surface of a sheet and a printing position of an image printed on the rear surface of the sheet, the following method has been di...
